A) What is systolic pressure? Diastolic pressure? B) Why is pressure a sensible reading to measure circulatory health? C) Explain the "lub-dub" sounds of the heartbeat. D) Why do blood pressure and heart rate change after exercise? E) How might blood pressure and pulse change lying down, at rest, and after exercise if someone else performed the activities? Why? F) Why is it important for blood to flow in only one direction?

Hydrostatic pressure is best described as: a. the uncoordinated contractions that occur during heart attacks. b. a premature ventricular contraction that signifies a skipped beat. c. a high point of pressure called diastolic blood pressure. d. an arterial vasodilation caused by carbon dioxide. e. the pressure of blood on the walls of arteries.
Systolic vs. diastolic pressure Classify the following as characteristic of systolic or diastolic blood pressure. One choice applies to both. Systolic Diastolic The lowest arterial pressure Decreases with distance from the left ventricle Occurs while the heart ventricles are relaxing The highest arterial pressure Reached during ejection of blood from the heart Normal level is 120 mm Hg Normal level is 80 mm Hg
